He it is Who hath caused those of the People of the Scripture who disbelieved to go forth from their homes unto the first exile. Ye deemed not that they would go forth, while they deemed that their strongholds would protect them from Allah. But Allah reached them from a place whereof they recked not, and cast terror in their hearts so that they ruined their houses with their own hands and the hands of the believers. So learn a lesson, O ye who have eyes!

Sahih Intl

It is He who expelled the ones who disbelieved among the People of the Scripture from their homes at the first gathering. You did not think they would leave, and they thought that their fortresses would protect them from Allah; but [the decree of] Allah came upon them from where they had not expected, and He cast terror into their hearts [so] they destroyed their houses by their [own] hands and the hands of the believers. So take warning, O people of vision.

Yusuf Ali

It is He Who got out the Unbelievers among the People of the Book from their homes at the first gathering (of the forces). Little did ye think that they would get out: And they thought that their fortresses would defend them from Allah! But the (Wrath of) Allah came to them from quarters from which they little expected (it), and cast terror into their hearts, so that they destroyed their dwellings by their own hands and the hands of the Believers, take warning, then, O ye with eyes (to see)!
